I agree with @benjiboy - one must make a choice between a neck strap or a small shoulder bag, and a bag always wins. My 35mm cameras all have a wrist strap on them and reside in a small shoulder bag along with film, cleaning cloth, smartphone, etc. This is far more practical than a neck strap.
Note, that trying to combine a neck strap with a shoulder bag is a bad idea. Most adjustable straps have buckles that can and will scratch a camera if placed in a confined space such as a bag. That's definitely true for Peak Design straps: they have huge aluminum buckles and if you put a camera with a Peak Design strap in a bag... let's just say black paint Leica owners won't be happy with this combination.
A neck strap is useful for extended photo sessions on a location, weddings, etc. Not for casually walking around.
